To all whom it may concern:

Be it known t at I, LOUIS- BAPTISTE, a citizen of'the United States, residing at the city of St. Louis, State of Missouri, have invented certain new and useful Improvements in'Mctal-(lntting Tools; and I do doclare the following to be a full, clear, and eX-' act description of theinvention, such as will enable others skilled in the art to which it i1 appertains to make. and use the same.

This invention relates to improvements-in metal cutting tools.

One object of the invention is to provide a tool designed particularly for the purpose o-f severing thetin fol or metalcap on the necks of bottles prior to removing A further object is to provide a device of this character having means whereby 'the depth atwhich'the cut is made may be regulated.

With these and other objects in view, the invention consists of certain novel features of construction, and combination and arrangement of parts as will be more fully described and claimed.

In theaccompanying drawings :Figure 1 is a central vertical sectional view of my improved tool showing the same applied toa bottle for cutting the cap thereon; Fig 2 is an inverted perspective view thereof; Flg. 3 is a horizontal sectional view taken on the line 3-3 of Fig.1; Fig. 4: is an-inverted perspective view of a modified form of the device; Fig. 5 is a horizontal sectional view thereof; Fig. 6 is a vertical cross section taken on the line 66 of Fig. 5; Fig. 7 is a central vertical cross sectional view of the form of the device shown in Fig. 1 illustrating a different means for regulating the out made by the blade; Fig. 8 is a bottom plan view showing a slightly modified form of cutting blade and a different shaped body.

In the embodiment of the invention as shown in the accompanying drawing, 1 denotes the bod of the device, which may be constructed 0 any suitable material and in any suitable shape, the same bein shown in the first seven figures of the drawlng as of rectangular form while in Fig. 8 the body is In the lower side of the body 1 is a circular cap engagingv shown as'being circular.

recess or socket' 2 which is adapted to receive the head and cap of the bottle as indicated in Fig. 1 of the drawings.

In one end or side of the body 1 near the bottom thereof is one-or more'slots 3, one of which is here'shown.

cuts through or intersects the socket or recess 2. Engafged with the slot 3 is a cutting blade or kni 4 the edge of which is pro vid'ed with saw teeth 4* and projects a suitable distance into and across one side of the socket 2, as shown. The blade or knife} is pivotally connected cent'to one edge of the body 1 as shown at 5. The opposite end of the blade 4 projects 'beyond the opposite edge ofthe body and iornisa handle 6 whereby the blade may be' swung inwardly to bring itscutting or saw tooth edge into the socket 2, to a greater or less extent t ereby permittin the device to'be used onbottle necks of di erent sizes and t position said-device eccentrically upon the object to be operated u on.'

In one'side of the be y 1 parallel with the edge' of the same through which the handle end of the blade'projects'is a bore 7 in which:

is arranged a coiled blade retracting spring 8 one end of which .is engaged with the inner end of the bore7 and theoth'er'end' is en gaged with a notch 9 in the'ha iidle' end of the blade as'cle'arly' shown inFig. 3 of the drawings. By th'us' arrangi'n it Wi'll be seen that the blade vvill'be retrao e'd after-each operations 'Wlien'retra'ctedby the spring the outward movement of the blade is limited bywa stop'pin 10"arran'gedin the body and across t slot as shown.

In order to regulate or gage the depth at which the cut is to be made in the cap I preferably provide a gage or stop screw 11, which has an operative engagement with a threaded passage 12 in the top of the body. On the inner end of the screw is arranged a stop plate 13 which engages the top of the bottle cap when the device is placed thereon. On the outer end of the screw is an operating head 14 whereby the screw is adjusted to bring the stop plate to the desired position.

In Figs. 4, 5 and 6 of the drawings is shown a slightly modified form of the de vice. In this instance the cutter comprises The edge of the slot at one end and adja-" the span a therewith. By placing a a body 15 constructed in the same manner, and having the same form of depth gage 16, as the cutter shown in Figs. 1, 2 and 3 of the drawings. In the modified form re-' ferred to, the body 15 is provided with a blade'receiving slot'17 which intersects the socket in the body, and .in said slot is arranged a blade 18 having a straight, plain cutting edge. The blade 18 in this form of the device 1s rigidly secured in operative po-;

ferent means for regulating the depth of the cut formed by the blade. In this instance, spacing disks or wads 21 are provided, one or more of which are placed in the inner end of the socket or recess to receive the end of the bottle cap when the device is engaged reater or less number of disks or wads in t e socket it will be readily seen that the location of'the out made by the blade will be regulated.

In Fig. 8 of the drawing is shown another modified form of the device. In this instance the body 22 of the device is shown as being of circular form and as provided with.

a fixed blade 23 arranged as shown and as having its central portion. curved or of segmental form to fit the curvature of the bottle cap with which it is engaged. While I have herein shown the curved blade 23 as applied to a circular form of body it will be obvious that this form of blade may be appliedto any other shape of body and that the blades shown in the other figures of the drawings may be applied to bodies of circular or any other form.

In the operation of the device, the socket therein is engaged with the cap on the neck of the bottle and the edge of the blade brought into engagement with the side of the cap. When thus engaged the body is rotated thereby carrying the edge of the cutter around the cap and severing the same, as

clearly shown in Fig. 1 of thedrawings.

From the foregoing description taken in connection with t e accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion and minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of the invention as claimed.

Having thus described my invention, what Iclaimis:- v

A metal cutting tool comprising a rectangular-shaped body portion having a receiving socket larger than the object to be operated upon, said body portion having a slit formed therein and intersecting the socket, a cutter one end of which is mov-ably located within-the slit and securedto said body and having its opposite end projecting beyond the latter, whereby the cutting edge of said cutter may be manually-brought in contact with the object to be operated upon,

a spring for yield-ingly holding the cutter out of operative position, means for limiting the outward movement of the cutter, an adjustable screw passing through the body, a plate movably secured to the lower end of said screw and substantially the same size as the socket in the body portion whereby said plate may be adjusted to and from the receiving opening formed therein, and means forming a part of the outer end of-said screw whereby the plate is properly adjusted to vary the capacity of the socket, and the cutter thereby properly positioned upon the object to be operated upon.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

LOUIS BAPTIS'IE.
